District-based mortgage giant Fannie Mae has named one of its own, David Benson, to succeed departing Chief Financial Officer Susan McFarland.

Benson, 53, has been with Fannie since 2002, when he joined the company as assistant treasurer. He has been promoted six times in the past seven years, and since September has been executive vice president of capital markets, securitization and corporate strategy.

Fannie (OTC: FNMA) announced McFarland’s departure several weeks ago. McFarland, 52, will officially step down the day after the company issues its annual report to the Securities and Exchange Commission, which should come any day, though she will stay for a few months as an adviser during a transition period.
